Fiberglass Unistrut For Corrosive and Non-Conductive Applications

Standard metal framing strut is not always suitable for chemical plants, refineries, pulp and paper mills, desalination facilities, and wastewater treatment plants. Hot dip galvanized, stainless, or strut coated with our proprietary Defender finish are options for these types of applications, but prolonged exposure in a caustic or corrosive environment will damage even the most durable Unistrut materials.  And when sparks and explosion hazards get thrown into the mix, a non-conductive material is sometimes the only option.  Whether your application requires exceptional corrosion resistance or an intrinsically safe material, Fiberglass Unistrut is worth consideration when metal is not a viable option.

How To Specify Fiberglass StrutWhen specifying fiberglass channel we need to consider common variables such as temperature, chemical environment, load conditions--AND flange profile. Temperature Range Fiberglass Unistrut is manufactured in five different materials to provide optimal performance under a wide range of temperatures.fiberglass channel temperature ranges by material 

Chemical ResistanceEach resin family has a set of unique physical properties. Use the charts below to specify the proper Fiberglass strut for your specific application. The test result results below reflect immersion for 24 hours. Less severe exposure (spills, splashes, and vapor condensate) will exceed the performance results indicated in the sample tables below:

Fiberglass Unistrut Load Data

We offer load data for fiberglass channel, fittings, and accessories in the Fiberglass Unistrut Catalog.  Please note this catalog is available in downloadable, PDF format for handy reference.

Aickinstrut and Fiberglass Unistrut Flange Profiles – Understanding The Difference

Some folks mistakenly assume that Aickinstrut and Fiberglass Unistrut are compatible.  Although both Aikinstrut and Fiberglass Unistrut are similar in many ways (corrosion resistance, non-conductive, non-metallic materials), the channel profiles are different.

 Fiberglass Channel Flange Styles

Unistrut fiberglass channels, except the SST series, have the Aickinstrut flange design which provides reliable interlocking of components and accessories.  Remember, standard framing components such as pipe clamps and strut nuts will not work with the Aikinstrut flange design.  The Unistrut SST profile is similar to the profile of standard metal channel and is compatible with standard 1-5/7” metal channel fittings and components.

Key Takeaways

  • Fiberglass Unistrut is ideal for corrosive and non-conductive applications
  • Aickinstrut and Fiberglass SST Profiles are different – specify the proper fiberglass nuts, fittings, and related hardware to ensure compatibility
  • Technical data, including temperature ranges, chemical resistance, and load data is available in the Fiberglass Unistrut Catalog

Applications requiring non-metal channel, fittings, and hardware are ideal for Fiberglass Unistrut.  Specification of fiberglass channel will give you all of the benefits associated with metal channel--ease of installation, adjustability, and reuse—combined with durability and safety.
